In daily use

Once paired with a compatible Zigbee hub, the DHI-HY-GC20D-R8 sends real-time CO concentration alerts to your smartphone, allowing you to respond even when away from home. The detector responds to dangerous CO levels according to EN 50291 thresholds: at 50 ppm it alarms within 60–90 minutes, at 100 ppm within 10–40 minutes, and at 300 ppm in under 3 minutes. A low-battery indicator and audible end-of-life signal eliminate guesswork about device status, while the white, low-profile housing blends discreetly into any room.
